# Voltage and Currents in Complex Circuits

EANDM-WYVS15

Consider the accompanying circuit diagram. A battery with a voltage of $20\,V$ is hooked up to 4 resistors in the configuration as shown. The current through the $5\Omega$ resistor is measured to be $1\,A$.

What is the value of the resistor labeled $R$?

What is the value of the current ($I$) leaving the battery?
