Question
The diagram shows the time variation of the current through an electrical heater when it is plugged into a 220 V, 60 Hz outlet. What is the peak voltage?
Correct, computer gets: 3.11E+02 V
Hint: Use the relation between the peak voltage and the rms voltage.
4.
What is the rms value of the current drawn by the heater?
Correct, computer gets: 7.07E+00 A
Hint: Use the relation between the peak current (graph) and the rms current.
5. [1pt]
What is the resistance of the heater?
Correct, computer gets: 3.11E+01 ohm
Hint: Ohm's law
6.
If t1 = 0.01 s, what is the value of t2
JUST NEED HELP WITH QUESTION 6 :)

if t1 = 0.01 s, what is the value of t2
t2 = t1 + T + T/2 = 0.01 + 1/60 + 1/60*2 = 0.01 + 0.0167 + 0.0083 = 0.035 s
