How much current flows through a 4 ohm resistor?
Hence, the current flowing through the resistor R1 (4 ohms) is 1A.
What is the current across the 4 ohm resistor using Thevenin’s theorem?
Using voltage divider, Vth= 2*10/(2+1)=6.67V. On drawing the Thevenin equivalent circuit, we get Rth, 4 ohm and Vth in series. Applying ohm’s law, I=Vth/(4+Rth)= 0.86A. This discussion on Calculate the current across the 4 ohm resistor.
What will be the work done in a resistor of 20 ohm carrying 5A of current in 3 hours?
9. Calculate the work done in a resistor of 20 ohm carrying 5A of current in 3 hours. Explanation: To find power: P=I2R=52*20=500W=0.5kW. To find Work done: W=Pt=0.5*3=1.5kWh.
How to find the current through a resistor?
Example 1: Finding current through a resistor using KCL, KVL Ohm’s Law – YouTube Using repeated application of Ohm’s Law, KCL and KVL to find the current/voltage in a circuit (Example 1)For another example see: https://youtu.be/TzpkyhK_Idc
How to calculate voltage current and resistance with Ohms Law?
The team of a calculator-online provided a simple and efficient tool known as “ohms law calculator” through which you can readily find out the value of voltage (V), current (I), power (P), and resistance (R) concerning simple ohm’s law formula. However, two of these values should have to be known to figure out the remaining two values.
How does ohm’s law work in a parallel circuit?
Ohm’s Law states that V=I*R, where V is voltage, I is current and R is resistance. In a series circuit, the voltage drop across each resistor will be directly proportional to the size of the resistor. In a parallel circuit, the voltage drop across each resistor will be the same as the power source.
How to calculate the voltage of a 10 Ma resistor?
[Voltage (V) = Current (I) x Resistance (R)] V (volts) = I (amps) x R (Ω) Find the voltage applied across 15 kΩ resistors when 10 mA current flows through it. Solution: Voltage (volts) = Current (amps) x Resistance (Ω); V = 10 mA x 15 kΩ; V = 150 V
