Question

For a battery, apply the relationship between power P, current i, and potential difference V.
Assignment question

Answer 1

Answer:

can be expressed in two different ways

. 

Where,

P is the Power and we measure it in watts or W. 

R is the resistance measured in ohms (Ω).

V = the potential difference applied across the ends of the conductor and is measured in Volts or simply V.

The second way to express the power resistance relationship is by using the following power and resistance equation:

Answer 2

Explanation:

Ohm’s law states that for some devices there is a relationship between electric potential difference, current, and resistance.

The equation is: I =\dfrac{\Delta V}{R}I=

R

ΔV

I, equals, start fraction, delta, V, divided by, R, end fraction

Where III is current, \Delta VΔVdelta, V is electric potential difference, and RRR is resistance.
