If a current of #4 A# passing through a circuit generates #12 W# of power, what is the resistance of the circuit?

Answer 1

0.75 ohms

When considering the current passing through a circuit and its resistance, the power generated by the circuit is given by:

#P=I^2R#

wherein

#P# is the power generated; #I# is the current through the circuit, and #R# is the circuit's resistance.

When we change the values, we get:

#12=(4)^2R#

#12=16R#

#R=12/16=0.75 Omega#

To find the resistance ( R ) of the circuit, use the formula ( P = I^2R ), where ( P ) is power, ( I ) is current, and ( R ) is resistance.

Given ( P = 12 , \text{W} ) and ( I = 4 , \text{A} ):

( 12 = (4)^2R )

( R = \frac{12}{16} )

( R = 0.75 , \Omega )

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.
