Series Circuit With Variable Resistor. You will need 3dmm s for this part of the experiment. The voltage across each resistor connected in series follows different rules to that of the series current.
The current through the circuit is the same for each resistor in a series circuit and is equal to the applied voltage divided by the equivalent resistance. Some materials have low resistance and are conductors. Set a potential difference vb 2v and determine the current through each resistor at a point before r1 between and r2.
However we cannot take the value of 9 volts and divide it by 3k 10k or 5k ω to try to find a current value because we don t.

The name of the circuit is derived from the letters that are used to denote the constituent components of this circuit where the sequence of the components may vary from rlc.
