The last thing we did with electricity is solving the currents, resistance, and voltage using multimeters and and by using mathematics. The first couple thing you need to know is that you measure voltage across what you are trying to measure other wise known as making a bridge. And you measure current through the multimeter arranged in the path before the object you are going to measure. Make sure you do this correctly with the multimeter or else Mr.Blake will make you think you broke it. To find this mathematically there is four steps. First of all you must find the REQ which is found by adding together all the resistors over 1. Then you find the Ibatt. which is found by dividing total voltage divided by REQ, the answer is then in amps. The next to steps is to find the voltage and current which can differ depending on the circuit.
