Question

What battery voltage is necessary to supply 0.51 A of current to a circuit with a resistance of 29 Ω? answer in:______volts

Answer 1

Ohm's law states that:

$I=\frac{V}{R}$

where V is the voltage, R is the resistance and I is the current; in this case the current is 0.51 A and the resistance is 29 Ohms. Plugging these and solving for the voltage we have:

$\begin{gathered} 0.51=\frac{V}{29} \\ V=29(0.51) \\ V=14.79 \end{gathered}$

Therefore, the voltage is 14.79 V
