What is the resistance seen across terminals A and B?
5 ohms
What is the formula to find equivalent resistance?
The equivalent resistance of a 4-Ω and 12-Ω resistor placed in parallel can be determined using the usual formula for equivalent resistance of parallel branches: 1 / Req = 1 / R1 + 1 / R2 + 1 / R3 Now the Ohm’s law equation (ΔV = I • R) can be used to determine the total current in the circuit.
What would be their equivalent resistance?
The equivalent resistance is where the aggregate resistance connected either in parallel or series is calculated. Essentially, the circuit is designed either in Series or Parallel. Electrical resistance shows how much energy one needs when you move the charges/current through your devices.
What will be the equivalent resistance between A and D?
Now all the resistance between the points A to D becomes in series, Hence, we can add all of them and get the final equivalent resistance. Hence, we can conclude that option (C) R=30Ω is the correct answer.
What is the resistance in a parallel circuit?
A parallel circuit has two or more paths for current to flow through. You can find total resistance in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 +… Rt = R (t)otal. If one of the parallel paths is broken, current will continue to flow in all the other paths.
Does voltage stay the same in series?
2. In a series circuit the current is the same at any particular point on the circuit. 3. The voltage in a series circuit, however, does not remain constant.
What is best series or parallel?
The main thing to remember is that wiring in series will increase your voltage, while wiring in parallel will increase your amperage. Both of the voltage and amperage need to be considered when designing your system, especially when it comes to finding an inverter that will work best for you.
Is current the same everywhere in a parallel circuit?
In parallel circuits the current splits up so each branch has a different effective resistance (in each of the separate branches one can use the series rule again). Due to this, the current isn’t the same everywhere in a parallel circuit. Most basic concepts that must be understood here are “Voltage” and “Current” .
Which resistor has the greatest current going through it?
Greatest: 6-ohm resistor; Least: 4-ohm resistor.
