Why do some electronic devices need grounding? Answer: Grounding electronic devices provides a safe path for excess electrical current to disperse into the earth, protecting users from electric shock and preventing damage to the device. Reasoning: Some electronic devices need grounding to ensure safety and proper functioning. Grounding provides a …

Answer: If you touch both terminals of a 12V battery, you create a closed circuit, allowing current to flow through your body, potentially causing electric shock, burns, or even death. Reasoning: When you touch both terminals of a 12V battery, you complete the circuit, allowing electricity to flow through your …

Answer: Neither 50Hz nor 60Hz frequency in 120V/230V electricity is inherently more dangerous. The danger primarily depends on factors like current, duration of exposure, and individual susceptibility to electric shock. Reasoning: The danger of electric shock is not solely determined by frequency but also by other factors such as current, …

Answer: The lowest voltage that can potentially be lethal to humans is around 50 volts. However, the danger also depends on factors like current, resistance, and the path the electricity takes through the body. Reasoning: Threshold for Sensation: Voltages below 50 volts are often considered safe, as they may not …

Answer: Both AC and DC can be harmful, but the severity of harm depends on various factors like voltage, current, and duration of exposure. Reasoning: he harmfulness of a current depends on factors such as voltage, current intensity, and duration of exposure. Both AC (alternating current) and DC (direct current) …

Answer: Yes, 3000 volts can hurt a human. Electric shock at this voltage level can cause severe injury or even be fatal. Reasoning: At 3000 volts, electrical currents can pass through the human body, disrupting normal physiological functions. This can lead to tissue damage, burns, and interference with the nervous …

Answer: Connecting a battery directly to an AC supply can result in damage to the battery, potential leakage, overheating, and, in extreme cases, may lead to a fire or explosion. Reasoning: Batteries are designed for DC (direct current) input, and connecting them to an AC (alternating current) supply can cause …

Answer: No, a fuse is designed to protect devices from overcurrent, not to prevent electrocution. Reasoning: No, a fuse will not stop a person from being electrocuted. A fuse primarily functions as a protective device against overcurrent situations in an electrical circuit. Its primary purpose is to break the circuit …

Answer: Both current and voltage are important in electrical systems, but their significance depends on the context. In general, neither matters more than the other; they are interrelated through Ohm’s Law (V = I * R). The importance of current or voltage depends on the specific application and the characteristics …

Which Current Is More Dangerous AC or DC? Answer: In terms of physiological effects on the human body, AC (Alternating Current) is generally considered to be more dangerous than DC (Direct Current) at certain frequencies and amplitudes. This is primarily due to the “let-go” phenomenon and the potential for sustained …

Answer: Current is usually more fatal than voltage. The severity of an electric shock depends on the amount of current passing through the body, with higher currents being more dangerous. Voltage, on the other hand, determines the potential for current flow. Reasoning: While voltage represents the force or pressure pushing …

Answer: You can feel a shock at voltages as low as 50 volts, but the severity and potential harm increase with higher voltages. Reasoning: Voltage is a measure of electric potential difference. The human body is a conductor, and when exposed to voltages above 50 volts, electrical currents can flow …

Answers: Birds don’t get shocked on power lines because they do not provide a path to ground for the electrical current. The electricity flows through the wire, and as birds are not in contact with the ground or another conductor, they do not complete a circuit and, therefore, do not …
