True or false. There is only an induced voltage in a coil of wire if the magnetic flux through the coil of wire changes.​

You are about to open a container of soy milk but notice that there are instructions to “shake well before serving.” the soy milk is most likely a

Clothes dryer uses about 7 amps of current from a 240 volt line. how much power does it use?

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
