A 70 ohm resistor is connected to a 6.7 V
battery in the circuit below.When the switch is closed, calculate the
current I.
Answer in units of A.
recall that I = V/R
where
I = current (in Amperes)
V = voltage (in Volts)
R = resistance (in Ohms)
substituting,
I = 6.7/70
I = 0.0957 A
hope this helps~ :)
thanks,(:
To calculate the current in the circuit, we can use Ohm's Law, which states that the current (I) flowing through a conductor is equal to the voltage (V) across the conductor divided by the resistance (R) of the conductor.
The formula for Ohm's Law is: I = V / R
In your case, the voltage (V) is given as 6.7 V, and the resistance (R) is given as 70 ohms. Plugging these values into the formula, we can calculate the current (I):
I = 6.7 V / 70 ohms
To perform this calculation, divide 6.7 by 70:
I ≈ 0.0957 A
Therefore, the current I is approximately 0.0957 Amperes.
