a tool used for cutting wires
Earth (ground) connection
return path for electric current, essential for circuit completion
a type of electrical insulation
a method for increasing voltage
a way to store electrical energy
True/False: Fuses are designed to increase current flow in a circuit
True
False
Fuses are designed to regulate voltage
Fuses are designed to decrease current flow
Relay
operated switch used to control high-current circuits
a device that stores electrical energy
a type of battery used in circuits
a component that amplifies signals
Ohm’s Law
@@V = I \times R@@ (Voltage = Current × Resistance)
@@V = I + R@@ (Voltage = Current + Resistance)
@@V = I / R@@ (Voltage = Current ÷ Resistance)
@@V = I - R@@ (Voltage = Current - Resistance)

controls the vehicle's navigation system
regulates tire pressure
True/False: The battery is recharged by the alternator while the engine is running
True
False
Only when the car is idle
Only during the night

a safety switch that prevents overloads
Circuit breaker
device protecting electrical circuits from overload
a tool for measuring electrical current
a type of electrical connector
a device for increasing voltage
Starter motor
motor that turns engine over to start vehicle
a device that charges the battery
a component that regulates fuel flow
a mechanism for cooling the engine
Automotive electrical system
A system of components supplying and controlling electricity in vehicles
A type of fuel used in vehicles
