voltmeter
measures potential difference b/t two points in the circuit.
Mounted in parallel.
measures potential difference b/t two points in the circuit.
Mounted in parallel.
series
when one component is arranged one after the other with no other circuit branches possible

The current is identical in the entirety of the circuit
when one component is arranged one after the other with no other circuit branches possible

The current is identical in the entirety of the circuit
parallel
components are arranged so that current throughs each independent of the path through others.

The potential difference across parallel branches are equal.

(resistivity) x (length) / (cross sectional area)
Electric Power
Power = current X voltage
units: Watts = joules/sec
Power = current X voltage
units: Watts = joules/sec
