Circuits
Series circuits
Electric circuit with one branch.
The parts of the circuit are wired one after the other having the same amount of current. If you disconnect one there is no current.
Parallel circuits
It has two or more branches.
They can be turn on and off separately.
Open circuits
When any part of a series circuit is disconnected there is no current.
Removing a battery from a graphic calculator. is an example.
Safety devices
Fuse
It has a small metal that melts when the current is too high.
When it melts it causes a break in the circuit stopping the curren.t
It has to be replaced for it to be able to enable the current again.
Circuit Breaker
It is used to prevent a circuit from overhaeting.
A switch atumatically flipped when the current is to high.
By doing this it opens the circuit.
Just by flipping it into its position is reset.
Electrical power
IS the rate in which electrical energy is converted into another form of energy.
Formula: Electrical power (watts) = current (amperes) x voltage difference (in volts). P=IV
Electrical energy
Formula: Electrical energy (in kWh) = electric power(kW) x time (in h). E=Pt.
