Answer :
The total voltage of four alkaline D batteries placed in series is 6 volts, as in series connection, voltages add up. Each D battery has a voltage of approximately 1.5 V.
When Alkaline D batteries are placed in series, the total voltage of the batteries is the sum of the individual voltages. Since each alkaline D battery has a voltage of approximately 1.5 V, four batteries in series will produce a total voltage of:
1.5 V + 1.5 V + 1.5 V + 1.5 V = 6 V
Therefore, the correct answer is B. 6 V. This is based on the principle that connecting cells in series results in the sum of their individual voltages. Alkaline batteries are known to provide consistent voltage, increased capacity, and reliable operation in a wide temperature range. One disadvantage is their higher cost compared to other battery types.
Voltage is also defined as the electric pressure, potential difference or electric tension. Volt is the unit which is used to express the voltage or potential difference. Here the total voltage is 36V. The correct option is D.
The total work required to move a unit of charge between two points in a static electric field is defined as the voltage. It is the difference in the electric potential between two points.
The total voltage in a series connection is equal to the sum of all the individual voltage drops in the circuit.
V = 9 + 9 + 9 + 9 = 36V
Thus the correct option is D.
