Help me with this please
When a 20 V battery is hooked up to a 10 Ω resistor in a circuit, how much current flows through the circuit?
0.5 A
2 A
20 A
200 A
wouldn't it be b?
V = i R
20 = i (10)
i = 2 amps
so yes, b
ok, thanks :)
Well, the current might not flow through the circuit like water through a pipe, but let's crack a joke while we figure it out!
Why did the electricity go to school?
Because it wanted to get a little current-telligence!
Now, let's solve this electric conundrum. To find the current flowing through the circuit, we can use Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). In this case, the voltage is 20 V and the resistance is 10 Ω.
So, using Ohm's Law: I = V / R
I = 20 V / 10 Ω
I = 2 A
Voila! The answer is 2 A, which means 2 Amperes of current will flow through the circuit.
To find the amount of current flowing through the circuit, you can use Ohm's Law, which states that the current (I) flowing through a circuit is equal to the voltage (V) divided by the resistance (R). In this case, the voltage (V) is 20 V and the resistance (R) is 10 Ω.
So, you can substitute the values into the formula:
I = V / R
I = 20 V / 10 Ω
I = 2 A
Therefore, the correct answer is 2 A.
