**Battery Configuration:**
The battery is composed of three cells connected in parallel. This means that the positive terminals of all three cells are connected together, and the negative terminals are also connected together.
**Given Data:**
- Emf of each cell: 1.4 volts
- Internal resistance of cell 1: 0.25 ohms
- Internal resistance of cell 2: 0.20 ohms
- Internal resistance of cell 3: 0.10 ohms
- Load resistance: 1.5 ohms
**Calculating the Equivalent Internal Resistance:**
To calculate the equivalent internal resistance of the battery, we need to consider the internal resistances in parallel. The formula for calculating the equivalent resistance of resistances in parallel is:
1/Req = 1/R1 + 1/R2 + 1/R3
Substituting the given values:
1/Req = 1/0.25 + 1/0.20 + 1/0.10
Simplifying:
1/Req = 4 + 5 + 10
1/Req = 19
Req = 1/19
Therefore, the equivalent internal resistance of the battery is 1/19 ohms.
**Calculating the Total Current:**
To calculate the total current flowing through the circuit, we can use Ohm's Law:
V = I * R
Where V is the emf of the battery and R is the total resistance.
Substituting the given values:
1.4 = I * (1.5 + 1/19)
Simplifying:
1.4 = I * (1.5 + 0.0526)
1.4 = I * 1.5526
I ≈ 0.901 A
Therefore, the total current flowing through the circuit is approximately 0.901 A.
**Calculating the Terminal Voltage:**
The terminal voltage of the battery can be calculated using the formula:
Vt = emf - I * req
Substituting the given values:
Vt = 1.4 - 0.901 * (1/19)
Simplifying:
Vt = 1.4 - 0.901 * 0.0526
Vt = 1.4 - 0.0474
Vt ≈ 1.35 V
Therefore, the terminal voltage of the battery is approximately 1.35 V.
Hence, the correct answer is option B. 1.35 V.
The battery is composed of three cells connected in parallel. This means that the positive terminals of all three cells are connected together, and the negative terminals are also connected together.
**Given Data:**
- Emf of each cell: 1.4 volts
- Internal resistance of cell 1: 0.25 ohms
- Internal resistance of cell 2: 0.20 ohms
- Internal resistance of cell 3: 0.10 ohms
- Load resistance: 1.5 ohms
**Calculating the Equivalent Internal Resistance:**
To calculate the equivalent internal resistance of the battery, we need to consider the internal resistances in parallel. The formula for calculating the equivalent resistance of resistances in parallel is:
1/Req = 1/R1 + 1/R2 + 1/R3
Substituting the given values:
1/Req = 1/0.25 + 1/0.20 + 1/0.10
Simplifying:
1/Req = 4 + 5 + 10
1/Req = 19
Req = 1/19
Therefore, the equivalent internal resistance of the battery is 1/19 ohms.
**Calculating the Total Current:**
To calculate the total current flowing through the circuit, we can use Ohm's Law:
V = I * R
Where V is the emf of the battery and R is the total resistance.
Substituting the given values:
1.4 = I * (1.5 + 1/19)
Simplifying:
1.4 = I * (1.5 + 0.0526)
1.4 = I * 1.5526
I ≈ 0.901 A
Therefore, the total current flowing through the circuit is approximately 0.901 A.
**Calculating the Terminal Voltage:**
The terminal voltage of the battery can be calculated using the formula:
Vt = emf - I * req
Substituting the given values:
Vt = 1.4 - 0.901 * (1/19)
Simplifying:
Vt = 1.4 - 0.901 * 0.0526
Vt = 1.4 - 0.0474
Vt ≈ 1.35 V
Therefore, the terminal voltage of the battery is approximately 1.35 V.
Hence, the correct answer is option B. 1.35 V.
