Question

A 10.0 Ω resistor is in parallel with a 30.0 Ω resistor and supplied by a 45.0 V battery. What is the total current drawn from the battery?

A. 0.003 A

B. 1.10 A

C. 6.00 A

D. 338 A

Answer 1

here the total resistance is:
\[\Large R = \frac{1}{{\frac{1}{{10}} + \frac{1}{{30}}}} = ...\]

Answer 2

7.5?

Answer 3

ok! so the requested current is:
\[\Large I = \frac{{\Delta V}}{R} = \frac{{45}}{{7.5}} = ...amperes\]

Answer 4

6! so our solution is choice C? 6.00 A?

Answer 5

that's right!

Answer 6

yay! thanks!:D
