Question

According to Ohm’s law, determine the calculated current for these values in Table A. voltage = 5 V, resistance = 20 Ω: A voltage = 20 V, resistance = 20 Ω: A voltage = 50 V, resistance = 20 Ω: A

Answer 1

Answer:

0.25 A

1.00 A

2.50 A

Explanation:

Answer 2

Answer:

0.25 A, 1.00 A, 2.50 A

Explanation:

Ohm's law is summarized by the equation:

$V=RI$

where

V is the voltage

R is the resistance

I is the current

Re-arranging it, we have an expression for the current:

$I=\frac{V}{R}$

Solving for the different cases, we have:

voltage = 5 V, resistance = 20 Ω: $I=\frac{5}{20}=0.25 A$

voltage = 20 V, resistance = 20 Ω: $I=\frac{20}{20}=1.00 A$

voltage = 50 V, resistance = 20 Ω: $I=\frac{50}{20}=2.50 A$
