How much power is produced if a voltage of #4 V# is applied to a circuit with a resistance of #8 Omega#?

Answer 1

Amelia Adams

2 Watts

Since #P=VI# and by Ohm's law, #V=IR# and hence #I=V/R# then substituting we get

#P=V^2/R#

Power is thus 16/8= 2W.

The power ((P)) in a circuit can be calculated using the formula:

[ P = \frac{V^2}{R} ]

where:

(P) is the power,
(V) is the voltage (4 V),
(R) is the resistance (8 ohms).

Substitute the given values into the formula to find the power produced.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
