Problem : 1 / 2

#PROBLEM-59145

Four resistors, $R_1=7 \space \Omega$ , $R_2=8 \space \Omega$ , $R_3=8 \space \Omega$ , and $R_4=2 \space \Omega$ are connected in series to a 59-V source. What is the total resistance of the circuit?

#PROBLEM-59146

If $R_4$ were replaced by another resistor such that the total resistance of the circuit is 74 $\Omega$ , what would be its value?
