Honors Physics - 2nd Semester Finals Review - Part 2

Which rule is NOT a rule for parallel circuits?

• The voltage is the same across all branches

• The current is the same through all branches

• The total resistance is less than the smallest branch resistance

• If one branch fails, the others keep working

Given a circuit with a battery of 94 V and 6 A, what is the resistance?

• 15.67 Ω
