Verified answer
Answer:
4.) C. 2 amps.
Given: V=10volts, R=5ohm
Solution: I=V/R
=10volts/5ohm
=2 Amps.
5.) D. 8ohm
Given: V=40volts, I=5amps
Solution: R=V/A
=40volts/5amps.
=8ohm
6.) D. 21 volts
Given: I=7amps, R=3ohm
Solution: V=IR
=(7amps)(3ohm)
=21 volts
7.) B. current will increase
8.) C. a circuit
9.) B. 0.33ohm
Given: V=14.5 volts, I=43.5amps
Solution: R=V/I
=14.5volts/43.5amps
=0.33ohm
10.) B. 1 volt
Given: I=1amp, R=1ohm
Solution: V=IR
=(1amp)(1ohm)
=1 volt
Hope this helps!
