13.1. The Big Ideas http://www.ck12.org
- Draw the schematic of the following circuit.
- What does the ammeter read and which resistor is dissipating the most power?
- Analyze the circuit below.
a. Find the current going out of the power supply
b. How many Joules per second of energy is the power supply giving out?
c. Find the current going through the 75Ωlight bulb.
d. Find the current going through the 50Ωlight bulbs (hint: it’s the same, why?).
e. Order the light bulbs in terms of brightness
f. If they were all wired in parallel, order them in terms of brightness.
