Please help me its very urgent :-

What determines the following? 3. How much current is supplied (at a constant voltage) by an ideal voltage source. b. How much voltage is supplied (at a constant current) by an ideal current source.An automotive battery is rated at 120 A-h. This means that under certain test conditions it can output 1 A at 12 V for 120 h (under other test conditions, the battery may have other ratings). a. How much total energy is stored in the battery? b. If the headlights are left on overnight (8 h). how much energy will still be stored in the battery in the morning? (Assume a 150-W total power rating for both headlights together.)A car battery kept in storage in the basement needs recharging. If the voltage and the current provided by the charger during a charge cycle are shown in Figure P2 8, a. Find the total charge transferred to the battery. b. Find the total energy transferred to the battery. 12 2 3 t, hours 10 It), amps 1 t, hours Figure P2.8A car battery kept in storage in the basement needs recharging. If the voltage and the current provided by the charger during a charge cycle are shown in Figure P2.8, a. Find the total charge transferred to the battery. b.

The charger voltage is such that the current into the battery does not exceed 100 mA, as shown in Figure P2.10. The charger's voltage increases to the maximum of 9 V, as shown in Figure P2.10. The battery is charged for 6 h. Find: a. The total charge delivered to the battery. b. The energy transferred to the battery during the charging cycle. Hint. Recall that the energy. w. is the integral of power, or P = dwot. Battery velupe "WO= 6.81 +0.19 202V, Ost
