An electric dryer with an equivalent series resistance and inductance of values 13 ωω and 46 mhmh is plugged into a standard 240v(rms) 60hz wall socket. you may assume the phase of the source voltage is zero. a) calculate the load current.

Given:

R = 13 Ω

L = 46 mH

V = 240 V(rms)

f = 60 Hz

Formula used:

Solution:

Now, using the above formula for :

= 17.34 Ω

From the above formula for  :

= (6.64 - j8.86) A = A

= A

= 15.65cos(376.99t - 53.14)A

ok

explanation:

answer: 31, 5556. 952 seconds
