If we use the simple application of Ohm's law where voltage (E) equals current (I) times resistance (R), or E = I x R, all we need to do is plug in values. If E = I x R and I = 8 amps and R = 15 ohms, E = 8 x 15 = 120 volts.
The path of least resistance.
The apparent answer to the question would be (100 W)/(120 V) = 0.8333 A, assuming that, as a pure resistance load, the light bulb has a power factor close to 1.0.
Current will be decreased because of the resistance of the ammeter added to the circuit's resistance. In other words total resistance increases.
A: As current approaches infinity on a device it is known as a current source.

The resistance of the load is what causes an electric current to flow in a circuit.
The resistance of the load is what causes an electric current to flow in a circuit.
I = E/R
An electric current follows the path of least resistance.
I am not sure how the two objects of equal resistance are supposed to be connected. But for a current to flow, for example across a resistor, there must be a voltage difference between the terminals of this resistor.
That depends on the resistance connected. Use Ohm's Law: V=IR. Solving for current: I = V/R. If nothing is connected, there will be no current (infinite resistance).
40 A -providing the voltage remains constant.
The formula is Resistance= Voltage/ Amps(current) In your example: R=50/2.5, so the answer is 20 ohms.
resistance refers to the resistance of flow of electric current wile a capacitor is an electric device that stores energy.
electric current
no
Ohms law states that E=I * R, or voltage equals current times resistance. Therefore current equals voltage divided by resistance. 120v divided by 16 ohms equals 7.5 amps.
