Shown below is a circuit that supplies energy toa device, The device is a load resistor which isequal to 6 ohms. "A" is a meter that can monitorthe current of the circuit and there is anadjustable resistor called a dimmer "Rd". Theadjustable resistor is set to 2 ohms and thecircuit is supplied with a battery that gives apotential difference of 12 volts.If the switch is closed for1 hr, find the energysupplied to the device by the battery.while the switch is closed, if the load resistanceincreased would the potential difference acrossthe dimmer stay at its value, increase, ordecrease, and why?meterdimmer, R.Load, RWATER TANK
