Series Circuit With Variable Resistor. Electric circuits can be series or parallel. An ammeter measures current and a voltmeter measures a potential difference.
Each resistor in a series circuit has the same amount of current flowing through it. But i don t know what to look up to determine the voltage on the diode or what the current will be on the circuit now that it is added. So for the resistor on its own the current would be 9 100 0 09 a across the whole circuit.
The voltage across each resistor connected in series follows different rules to that of the series current.
But i don t know what to look up to determine the voltage on the diode or what the current will be on the circuit now that it is added. Simulate this circuit schematic created using circuitlab. Set a potential difference vb 2v and determine the current through each resistor at a point before r1 between and r2. Some materials have low resistance and are conductors.
