  2. Measurtw@ ourrev•bt avu voltage Current is measured in placed in (A) using an We say the ammeter is because it is in the main part of the circuit. Potential difference or voltage is measured in volts (V) using a component. We say a voltmeter is placed in part of the circuit. The current in a circuit flows from the , which is placed across a because it is not in the main end of the cell to the end. amps ammeter negative parallel positive series voltmeter voltage am ourrevtvt When electrons are moving through something an electrical is flowing. For The a current to flow there must be a bigger the voltage, the difference or the current that flows. The voltage is provided by bigger cell current t/æ tatte Cebu Symbol potential Units voltage Symbol for Units Quantity Charge Current Potential difference Energy Resistance
