Question

A household wiring circuit consists of a voltage source (ac power from the electric company) connected across many loads (resistances) in parallel. a.) Draw a circuit diagram showing the voltage source and three loads, e.g., a light bulb, a clock, and a TV set. I understand that they are all parallel simple enough. This is AC is it normal to just use the two dots with the squiggly line between the connections (in stead of say the potential difference symbol used for DC)? I believe there should be a switch and resistor before the light bulb. is this right? I don't understand how to place a TV on the diagram (first I'm not sure what the symbol would be for a TV and should there be a resistor and a capacitor since electricity is never fully disconnected from a TV maybe there is a symbol for this instance). ? The clock never turns off so there should only be a resistor with a direct wire connection? does there need to be a symbol for clock?

Explanation / Answer

You can straight away show the Bulb as a resistor, you can add a switch to it. For T.V. and clock,, as we do not know the internal circuitry of both T.V and clock, it is preferable to draw a box(with T.V or clock written on it) instead of using resistor or capacitor symbols. Switch can also be used for T.V
