What is the total current in a parallel circuit if each branch has a different resistance?
Total current depends on the total resistance only
The same current flows through each branch
Total current is the sum of currents in each branch
Total current is the average of all branch currents

How do you calculate the total resistance in a series circuit?
Use Ohm's Law
Add all resistances together
Use the formula 1 / ð ðĄ ð ðĄ ð ð = 1 / ð 1 + 1 / ð 2
Take the average of the resistances
