Parallel Circuits
A parallel circuit (Figure 17-3) is defined as a circuit having more than one current path. The factors governing the operations of a parallel circuit are listed here:
1. The same voltage exists across each branch of the parallel circuit and is equal to that of the voltage source.
2. The current through each branch of a parallel circuit is inversely proportional to the amount of resistance of the branch (I 5 E/R).
1. What is the formula for total current in a parallel circuit?
2. What is the formula for total voltage in a parallel circuit?
3. What is the formula for total resistance in a parallel circuit?
4. What is the formula for total power in a parallel circuit?
5. Four resistors, 2200 ohms, 2700 ohms, 3300 ohms, and 5600 ohms, are connected in parallel with a battery rated at 9 volts. Solve for all values of the circuit.
