Generate an image of an electrical experiment setup. In the center, there should be a battery that has a glossy exterior and is labeled as 6 volts. Connected to this battery through thin, metallic wires, we see a single pole single throw switch that's currently in a closed position. Further along the circuit, there is a 2.6 ohm resistor, identifiable by the colored bands on its cylindrical body. The background is a clean, lightly textured wooden table. Please note: no text should be included in this image.

a battery has an e.m.f of 6 volts and an internal resistance of 0.4 ohm.it is connected to a 2.6 ohm resistor through a SPST{single pole,single throw}switch.when the switch is closed,the potential difference between the terminals of the battery is,involts?

E = 6 Volts

r = 0.4 Ohms
R = 2.6 Ohms.

I = E/(r+R) = 6/(0.4+2.6) = 2 Amps. =
Current flowing in the circuit.

Vt = I*R = 2 * 2.6 = 5.2 Volts. = Potential difference between terminals
of the battery.

Vr = I * r = 2 * 0.4 = 0.8 Volts. =
Voltage lost across the internal resistance.

Vt + Vr = 5.2 + 0.8 = 6.0 Volts = Battery e.m.f.

To find the potential difference between the terminals of the battery when the switch is closed, we need to calculate the total resistance in the circuit.

The total resistance (R_total) can be found by summing the resistance of the resistor (R) and the internal resistance of the battery (r):
R_total = R + r

Given:
Internal resistance of the battery (r) = 0.4 ohm
Resistance of the resistor (R) = 2.6 ohm

Substituting the values:
R_total = 2.6 ohm + 0.4 ohm
R_total = 3 ohm

Now, we can use Ohm's Law to calculate the potential difference (V) across the terminals of the battery when the switch is closed. Ohm's Law states:
V = I * R_total

The current (I) flowing through the circuit can be determined using Ohm's Law again:
I = V / R_total

Given:
Electromotive force of the battery (emf) = 6 volts

Substituting the value of emf into the equation:
I = 6 volts / 3 ohm
I = 2 amperes

Now we can substitute the value of current (I) into the equation for potential difference (V):
V = (2 amperes) * (3 ohm)
V = 6 volts

Therefore, when the switch is closed, the potential difference between the terminals of the battery is 6 volts.
