Exam 37: Ohms Law

In a series circuit, all of the resistances are ____ and then substituted in Ohm's law together to equal total resistance (R).

The total current flow in a parallel circuit is the ____.

Find the current flow (amperes) in a headlight circuit with 0.9 ohms resistance. The battery voltage is measured at 11.8 volts. Round to the nearest tenth.

An automobile horn requires only 0.2 ampere. The resistance is 43 ohms. Find the voltage.

While starting the motor, 276 amperes are flowing. With a 12-volt battery, what is the resistance of the starting motor? Round to the nearest hundredth ohm.

The lighting system of an automobile draws 6.7 amperes at a battery voltage of 11.5. Find the resistance of the lighting system to the nearest thousandth ohm.

If resistance is increased, current flow is ____________________.

It should be noted that in a parallel circuit, the total resistance is ____ the lowest resistance in the circuit.

If voltage is increased, current flow is ____________________.

Ohm's law states the relationship of pressure, current flow, and ____________________ in an electrical circuit.
