What is the maximum equipment needed to determine the power dissipated in a resistor of unknown value?
1) a voltmeter, only
2) An ammeter only,
3) a voltmeter and an ammeter only
4) a voltmeter, an ammeter, and a stopwatch
what is the minimum equipment needed to detemine
Sorry it is what is the "minimum" not maximum
3. a voltmeter and an ammeter, only
Avoltmeter only
In order to determine the power dissipated in a resistor of unknown value, you can use a combination of a voltmeter and an ammeter. The voltmeter measures the voltage across the resistor, and the ammeter measures the current flowing through the resistor.
To calculate power, you can use the formula:
Power = Voltage * Current
Therefore, you need both the voltage (measured by the voltmeter) and the current (measured by the ammeter) to obtain the power dissipated in the resistor.
So, the correct answer would be option 3: a voltmeter and an ammeter only.
