Question

Describe with necessary theory, the method of measuring high resistance by leakage
method.​

Answer 1

Answer:

Leakage method is one of the most effective and accurate methods used to measure the value of very high resistances.

Explanation:

In leakage method, main concept used to calculate the value of resistance is the charging and discharging of a capacitor. A ballistic galvanometer is used to measure the amount of charge that the capacitor/condenser discharges.

In a laboratory, below are the list of items required in order to measure resistance via leakage method:

Ballistic galvanometer

Power supply / accumulator

Capacitor

Resistor whose value is to be measured)

Few connecting wires

Tapping key & morse key

Lamp and scale arrangement

Stop watch

Answer 2

Leakage Method

Explanation:

• Leakage method is one of the most effective and accurate methods used to measure the value of very high resistances
• High Resistance Measurement by Leakage Method is helpful for estimating extremely high estimation of Resistance. Advanced Multimeters or LCR meters are utilized to gauge the ordinary estimation of obstruction (by and large 1ω - 20MΩ) yet on account of exceptionally high estimation of opposition, these can't quantify with high precision
• Leakage Method is exceptionally precise approach to quantify the high estimation of opposition as a result of extremely delicate ballistic galvanometer with scale and light course of action and low estimation of capacitances utilized in the item. It is furnished with various estimations of obscure high protections on rotating determination and various estimations of capacitors
