(I X R)
If the battery produced 12.6 Volts what would be the current flow for a 6 Ohm resistor?
2.1 Amps
2.4 Amps
1.71 Amps
15 Amps
Based on the graph, which of the following would be true regarding the relationship of voltage and current?
As voltage increases, current decreases.
Voltage will not affect current.
As voltage decreases, current increases.
As voltage increases, current also increases.
What is the formula for resistance?
R = I / V
R = V / I
R = V x I
R = (V x I) / 2
What is the formula for current?
I = V / R
I = R / V
I = V x R
I = (V x R) / 2
What is the formula for voltage?
V = (I x R) / 2
V = I / R
V = R / I
V = I x R
If a charger for a tablet offers a voltage of 120V and has 240Ω of resistance, what is the amperage?
0.5A
2A
14,400A
28,800A
