... The total circuit resistance was calculated in question 15, which is 19.12 ohms. We can calculate the total circuit current using Ohm’s Law, or I=E/R, or 120V/19.12Ω, or 6.28 Amps. We can also calculate the current through the 24 ohm resistor similarly, or I=E/R, or 120V/24Ω, or 5 Amps. Notice that ...
