Problem

Two resistors

R_1 = 2\,\Omega

and

R_2 = 4\,\Omega

are connected in series with a battery so that the same current

I

flows through each. Which statement about the power dissipated in the resistors is correct? (a) Both resistors dissipate equal power (b) The

2\,\Omega

resistor dissipates twice the power of the

4\,\Omega

resistor (c) The

4\,\Omega

resistor dissipates twice the power of the

2\,\Omega

resistor (d) The

4\,\Omega

resistor dissipates four times the power of the

2\,\Omega

resistor
