Three cells each of emf 2v are connected in series with an ammeter,two resistors of resistance 2 ohms and 6 ohms and a switch
A.draw a circuit diagram of the arrangement
B.Calculate the total current that would flow in the electrical circuit
Can't draw diagams on this forum.
3 2v cells in series is 6 volts.
2 resisters connected in series(I assume). Total R = 2 + 6 = 8 ohms.
E = I*R.
You know E is 6 volts
You know R is 8 ohms.
Solve for I = current in amperes.

Three cells each of emf 2v are connected in series with an ammeter,two resistors of resistance 2 ohms and 6 ohms and a switch
A.draw a circuit diagram of the arrangement
B.Calculate the total current that would flow in the electrical circuit
A. To draw a circuit diagram of the given arrangement, follow these steps:
1. Draw a straight line to represent the circuit.
2. Place three cells in a series at one end of the line. Connect the positive terminal of the first cell to the negative terminal of the second cell and so on. Label each cell with "2V" to represent their emf.
3. Connect an ammeter in series with the cells. The ammeter should be placed after the third cell.
4. Place a resistor of 2 ohms in series with the ammeter. Connect one end of the resistor to the ammeter and the other end to the positive terminal of the third cell.
5. Connect a resistor of 6 ohms in parallel with the previously connected resistors. Connect one end of the 6 ohms resistor to the negative terminal of the third cell, and the other end to the negative terminal of the first cell.
6. Finally, add a switch in series with the resistors. Connect the switch between the positive end of the 2-ohm resistor and the negative terminal of the first cell.
B. To calculate the total current that would flow in the electrical circuit, follow these steps:
1. Determine the total resistance (Rt) of the circuit by applying the parallel resistance formula:
1/Rt = 1/R1 + 1/R2
where R1 = resistance of the 2-ohm resistor and R2 = resistance of the 6-ohm resistor.
1/Rt = 1/2 + 1/6
1/Rt = 3/6 + 1/6
1/Rt = 4/6
Rt = 6/4
Rt = 1.5 ohms
2. Apply Ohm's Law to calculate the total current (It) flowing in the circuit:
It = Et / Rt
where Et = total emf of the cells connected in series.
Et = emf of one cell * number of cells
Et = 2V * 3
Et = 6V
It = 6V / 1.5 ohms
It = 4A
Therefore, the total current that would flow in the electrical circuit is 4 Amps.
Pls I would be thankful for helping me.I n
eed to send it to school God willing tomorrow
