How much power is produced if a voltage of #3 V# is applied to a circuit with a resistance of #24 Omega#?

Answer 1

Isabella Alvarez

#P = 0.375 # Watts
or
#P = 375 * 10^-3 # Watts

We know:

#P = (V)^2/(R)#

Where #P# is power, #V# is Volt and #R# is resistance.

#P = 3^2/24#

#P = 9/24#

#P = 3/8#

#P = 0.375 # Watts or #P = 375 * 10^-3 # Watts

Apply the power formula: ( P = \frac{V^2}{R} ) Plug in values: ( P = \frac{(3 \ V)^2}{24 \ \Omega} ) Calculate: ( P = 0.375 \ W ) The power produced is (0.375 \ W).

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.
