Question

When E = 14 V and R = 1 Ω, the current is _________ amperes.

When E = 14 V and R = 4 Ω, the current is _________ amperes.
When E = 14 V and R = 8 Ω, the current is _________ amperes.
When E = 14 V and R = 12 Ω, the current is _________ amperes.

Answer 1

Current = Emf / Resistance

When E = 14 V and R = 1 Ω, the current is 14/1 amperes = 14 amp

When E = 14 V and R = 4 Ω, the current is 14/4 amperes = 3.5 amp

When E = 14 V and R = 8 Ω, the current is 14 / 8 amperes = 1.75 amp

When E = 14 V and R = 12 Ω, the current is 14 / 12 amperes = 1.16 amp

Answer 2

When E = 14 V and R = 1 Ω, the current is 14 A.

When E = 14 V and R = 4 Ω, the current is 3.5 A.

When E = 14 V and R = 8 Ω, the current is 1.75 A.

When E = 14 V and R = 12 Ω, the current is 1.166... A
(rounded to three decimal places).

Step-by-step explanation:

To calculate the current (I) using Ohm's law, we can use the formula:

I = E / R

where I is the current in amperes (A), E is the voltage in volts (V), and R is the resistance in ohms (Ω).
