a. What should the ammeter reading be?
b. what should the voltometer reading be?
Given:
V = 27 v
R = 18 ohm
I found the first one by using I = V / R which equals to 1.5 A. But im confused on how to find the voltometer.
If the voltmeter is across the resistor, it is 27 volts.
Ok, thank you
To determine the ammeter and voltmeter readings, we need to use Ohm's Law, which states that voltage (V) across a resistor is equal to the product of current (I) flowing through it and resistance (R):
V = I * R
Given the values:
V = 27 V
R = 18 Ω
a. Ammeter Reading (I):
To find the ammeter reading, we need to calculate the current flowing in the circuit. Rearranging Ohm's Law:
I = V / R
Substituting the given values:
I = 27 V / 18 Ω
Calculating this equation gives the ammeter reading.
b. Voltmeter Reading (V):
The voltmeter is connected in parallel to the resistor, which means it measures the voltage across the resistor. Therefore, the voltmeter reading will be the same as the applied voltage, which is given as 27 V.
There is no need for calculation here; the voltmeter reading is directly given as 27 V.
