1- An ideal Voltmeter is connected across the terminals of a 12 Volt battery and a light bulb with R = 4.5 ohms is also connected across the battery terminals. The Voltmeter reads 9.0 Volts.

(a) Draw and label a figure using electrical symbols

(b) Find the current, I, in the curcit.

(d) Find the power generated by the Emf of the battery.

2- The current in a wire varies with time as: I = 4.0A - (0.2A/s)t.

Find the charge, Q, that passes through a cross section of the wire in the time interval between t = 0s and t = 5.0s.
