(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

You are given a 120 V battery; a hair dryer designed to work properly at 120V, where its rated at 1200 W; and a mixer designed to work properly at 60v, where its rated at 120W. You also happen to have a supply of 60 ohm resistors.

a) determine the resistance of the hairdryer and the mixer at their rated voltages

B) what current is established in the mixer when its working properly

C) using the symbols shown, draw the connections needed to make both devices work simultaneously

Symbols

a resistor

a battery

a box with the letter h signfiying hair dryer

and a box signifying mixer

d) what power must the battery supply to run your circuit?

2. Relevant equations

3. The attempt at a solution

a)I think the resistance of the hairdryer is 12, but how would I found the mixers?

B) dont know how to approach this one?

c) same as above

d) wait wait... nope, dont know how to this one either.

My teacher likes to assign homework on stuff we havant learned yet :(
