Voltage and current in a parallel circuit l In a parallel circuit the voltage is the same across each branch because each branch has a low resistance path back to the battery. l The amount of current in each branch in a parallel circuit is not necessarily the same. l The resistance in each branch determines the current in that branch.

Advantages of parallel circuits Parallel circuits have two big advantages over series circuits: 1. Each device in the circuit sees the full battery voltage. 2. Each device in the circuit may be turned off independently without stopping the current flowing to other devices in the circuit.

Short circuit l A short circuit is a parallel path in a circuit with zero or very low resistance. Short circuits can be made accidentally by connecting a wire between two other wires at different voltages. l Short circuits are dangerous because they can draw huge amounts of current. l

Resistance in parallel circuits l Adding resistance in parallel provides another path for current, and more current flows. l When more current flows for the same voltage, the total resistance of the circuit decreases. l This happens because every new path in a parallel circuit allows more current to flow for the same voltage.

Electric Power, AC, and DC Electricity l The watt (W) is a unit of power. l Power is the rate at which energy moves or is used. l Since energy is measured in joules, power is measured in joules per second. l One joule per second is equal to one watt.
![Power in electric circuits l One watt is a pretty small amount of power Power in electric circuits l One watt is a pretty small amount of power.](https://slidetodoc.com/presentation_image/446df2d72f3df609e5275424241d8e23/image-21.jpg)
Power in electric circuits l One watt is a pretty small amount of power. l In everyday use, larger units are more convenient to use. l A kilowatt (k. W) is equal to 1, 000 watts. l The other common unit of power often seen on electric motors is the horsepower. l One horsepower is 746 watts.

Paying for electricity Electric companies charge for the number of kilowatt-hours used during a set period of time, often a month. l One kilowatt-hour (k. Wh) means that a kilowatt of power has been used for one hour. l Since power multiplied by time is energy, a kilowatt-hour is a unit of energy. l
