It depends on the resistor values
2. Which statement is true for a parallel circuit?
Current is the same through each resistor.
Voltage is divided among the resistors.
The reciprocal of total resistance is the sum of reciprocals of individual resistances.
Total resistance is the sum of individual resistances.
