2 Volts are needed to push one amp through a a 2 Ohm resistor. 1000000 Volts are needed to push one amp through a one megohm resistor.

Answer. Answer: Resistance: V = I R (volts = amps * ohm). A 1 ohm resistor will lose 1 volt when conducting 1 amp of current; a 10 ohm resistor will drop 10 volts when conducting one amp.

Answer: The circuit resistance will be 2 ohms.

6. What is the resistance of a curling iron that draws 12 A of current on a 120 V circuit? R = v= 120v = 100 Gu .

Answer. Explanation: The current is directly proportional to the voltage and inversely proportional to the resistance. This means that increasing the voltage will cause the current to increase, while increasing the resistance will cause the current to decrease.

144 ohms

Temperature difference is a necessary condition for the flow of heat. Similarly, a voltage difference is necessary for the flow of charge.

If you are referring specifically to a circuit made up of solid material, then protons are tightly bound and hence don’t flow and positive charge if any, is due to holes.

protons do move and current is the flow of negatively charged particles electrons… 🙂 not the positive charge.

The answer is: although it is convenient to think of the electron moving around the nucleus along circular paths, the correct description is a quantum mechanical one. In the more accurate quantum picture, the motion of the electron is described by probability functions and there is no fixed orbit.
