You find an NiMH battery has a Thevenin equivalent model of 1.5 V and 0.1 Ω.
a) Draw the equivalent circuit that represents the battery.
b) You use this battery to power a motor that has an equivalent resistance of 4 Ω.
(i) what will be the load current ?
(ii) How much power is delivered to the motor ?
c) You find a second battery with a Thevenin equivalent model of 1.5 V and 0.3 Ω and are curious about what happens when you use both batteries.
Since the motor is rated at 1.0 - 2.5 V, you place the two batteries in parallel to drive the motor.
(i) What is the new load current ?
(ii) Does it increase or decrease ?
(iii) Will the power dissipated by the load increase or decrease ?
