hi I'm dr. Bob and I'm a physicist different example resistors Motors source of power connected to the components to provide energy voltage source in a circuit provides the energy the circuit can a round-trip Loop through the circuit wires and through the various components give me the diagram to represent the Ozark representing wires resistors transistors capacitors there are different types of circuits two general categories circuits and parallel circuits series circuits have only one possible path for the current to flow along to be controlled by a single switch if the switch is open the circuit will work the circuit is broken string circus multiple tap the current flow should continue in this case is broken still continue to operate you may have two switches on either side of the hallway the lightning either switch to make or break the circuit to control your light Law relates voltage current and resistance and can be used to find if the other two are already known across the resistance add a resistance R has a voltage across it of V equals IR and current has a resistance equals it's a flashlight uses a light bulb with resistance how much current will flow through the / r equal 4 volts divided by 60 equals 0.066 amps direct current DC circuit where the current flows with a voltage V and a current I the electric power equals current times what is the power of a light bulb with 120 volts and amps of current power equals current times voltage 25 amp this is equal to 60 watts now what have we learned electrical circuits connected by wire to a power saw electrical circuits have a voltage source for example a battery this is connected to components of a circuit which could be light resistors Motors all devices series or parallel only one possible path for the current circuits multiple possible for the current to flow along equate you I equals V over R voltage across a resistance creates a current equals the voltage divided by the real voltage
