Explanation:
To convert a voltmeter into an ammeter, a shunt resistance is connected in parallel with the voltmeter.
Formula:
The current through the shunt resistance is given by I = V/R, where V is the voltage across the shunt resistance and R is the shunt resistance.
Given:
Range of voltmeter = 5V
Resistance of voltmeter = 300 ohm
Range of ammeter = 5A
Calculation:
To convert the voltmeter of range 5V into an ammeter of range 5A, we need to find the shunt resistance.
We know that the maximum current that can be measured by the voltmeter is 5V/300 ohm = 0.0167A.
To measure a current of 5A, the shunt resistance must be such that 5A flows through it when a voltage of 5V is applied across it. Using Ohm's law, we can find the resistance of the shunt as R = V/I = 5V/5A = 1 ohm.
Therefore, the shunt resistance needed to convert the voltmeter into an ammeter of range 5A is 1 ohm.
Conclusion:
In conclusion, to convert a voltmeter of range 5V and resistance 300 ohm into an ammeter of range 5A, a shunt resistance of 1 ohm must be connected in parallel with the voltmeter.
