A 2 micro farad capacitor is connected by closing a switch to a supply of 100 volts through a 1 mega ohm series resistor. Find the initial rate of rise of p.d across the capacitor and the time taken for the capacitor to be fully charged.

a 2 ohms and 3 ohms resistors in parallel are connected in series to a 4 ohms resistor. the combination is then connected to a 12v battery, having internal resistance of 1 ohms. Calculate the current in the 3 ohms resistor

With a 1200-W toaster, how much electrical energy is needed to make a slice of toast (cooking time = 1 minute)? At 7.0 cents / kW·h, how much does this cost in cents. Below is what I have so far where do I go from here

P=(1200 W)(1Kw/1000W) = 1.20 Kw

t= (1 Min)(1 / 60)=0.0167 Hr
