12\,\text{V}

ideal battery is connected between terminals

P

and

Q

of the resistor network described verbally below. • Between

P

and

Q

there are two distinct paths. • Path 1 contains a

40\,\Omega

resistor in series with a

20\,\Omega

resistor. • Path 2 contains a single

30\,\Omega

resistor. • The ends of Path 1 and Path 2 are joined together before connecting to terminal

Q

. Assume all connecting wires are ideal. (1) Calculate the equivalent resistance of the entire network between

P

and

Q

. Show your work. (2) Determine the current supplied by the battery. Include appropriate units in your answer.
