Here, we can see that the electric power is directly proportional to resistance on keeping I constant. When power increases, the resistance also increases, while keeping current I constant. However, when the resistance in the circuit decreases, power in the circuit also decreases, while keeping current I constant.

Hence, the current will become double.

The power dissipated in a resistor is given by P = V2/R which means power decreases if resistance increases. Yet this power is also given by P = I2R, which means power increases if resistance increases.

power is inversly proportional to resistance as power is the rate of flow of electrical energy through a conductor with potential diff n more energy is used for more resistance.

the thicker a wire is, the lower resistance it will have. Use the drop-down menus to complete the sentences. A thin wire has MORE resistance than a thick wire. A short wire has LESS resistance than a long wire.

First, the total length of the wires will affect the amount of resistance. The longer the wire, the more resistance that there will be. Wider wires have a greater cross-sectional area. Water will flow through a wider pipe at a higher rate than it will flow through a narrow pipe.

1 Answer. Resistance is directly proportional to the length of the wire, and inversely proportional to the cross sectional area of the wire. Doubling the length will double the resistance, but the wire also must get thinner as it is stretched, because it will contain the same amount of metal in twice the length.
