ECET 110 WEEK 1 HOMEWORK

Why do you never apply an ohmmeter to a live network?

What is the voltage across a 220 Ω resistor if the current through it is 5.6 mA?

What is the current through a 6.8 Ω resistor of the voltage drop across it is 24V?

What is the power delivered by a 6V battery if the current drain is 750mA?

The current through a 4k Ω resistor is 7.2mA. What is the power delivered to the resistor?
