Who needs a Map

• To turn on the TV and all the lights we need a circuit, it would depend on how it is wired

  There are two types of circuits.

• Series Circuits

• Parallel Circuits

Series Circuits

• Has only the path for electric charges to follow. if any part of the path breaks, the circuit is open and NOTHING WORKS

Parallel Circuits

• Is circuit with several different paths for charges to follow, if one part of the circuit break, the charges can still flow along the other parts

Multiple Choice

what is this circuit called?

• Series Circuits

• Parallel Circuits

Circuit overload

• Electrical circuits are designed to handle a limited amount of electricity. ... If there were no breaker in the circuit, an overload would cause the circuit wiring to overheat, which could melt the wire insulation and lead to a fire.

Circuit overload

• Overloaded circuit warning signs:

  Flickering, blinking, or dimming lights. Frequently tripped circuit breakers or blown fuses. Warm or discolored wall plates. Cracking, sizzling, or buzzing from receptacles. Burning odor coming from receptacles or wall switches. Mild shock or tingle from appliances, receptacles, or switches.

Multiple Choice

Electricity has many uses

• Devices that use electricity change electrical energy in to other types of energy, such as light or heat. we use electricity to heat our homes and cook our food.
