Maharashtra State Board: Class 11
Definition: Voltmeter
An instrument used to measure the potential difference between two points in an electrical circuit, always connected in parallel with the component across which the voltage drop is to be measured, is called a voltmeter.
Maharashtra State Board: Class 11
Law: Kirchhoff's Current Law (KCL) - Junction Rule
At any junction, the sum of currents entering = the sum of currents leaving.
\[\sum_{i=1}^nI_i=0\]
Example: I1 + I3 = I2 + I4. Based on conservation of charge.
Maharashtra State Board: Class 11
Law: Kirchhoff's Voltage Law (KVL) - Loop Rule
The algebraic sum of potential differences in a closed loop is zero.
∑IR + ∑E = 0 OR ∑E = ∑IR
Based on conservation of energy.
