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=(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=(V)/(29) \\ V=29(0.51) \\ V=14.79 \end{gathered}`

Therefore, the voltage is 14.79 V
