Directions: Read the following question and answer the following.
In a Vasundhra society, there was an electricity project. The electricity department observes the current and voltage flow in the circuits of five different buildings: Antilia, Mannat, Jalsa, KGF, and Elephanta, through which a current is passed for some time. When a current passes through a circuit, the resistance in the circuit generates heat.
The relation between voltage, resistance and current is given by the following formula:
V = I*R, where V = voltage, I = current and R = resistance.
The units of voltage and current is 'volts' and 'amperes' respectively.
When a current 'I' amperes passes through a resistor of resistance 'R' ohms for time 'T' seconds
the heat produced, Q = I2*R*T, unit of Q is Joules.
The ratio of the current in building Antilia and Mannat is 4:3 and the ratio of the resistances in Antilia and Mannat is 4:5. In building Antilia and Mannat, the sum of the time for which current is passed through is 27 seconds and the sum of the heat generated is 1731.6 Joules. The voltage in building Antilia is 9.6 volts. The ratio of the time for which current flows in building Mannat to that in building Jalsa is 3:2. In building Jalsa, the voltage is 24 volts and the numerical value of current(in amperes) is 10 more than the numerical value of resistance(in ohms). The heat generated in building Jalsa is 2880 Joules. The sum of the resistances through all the five buildings is 14.7 ohms. In circuit KGF, the ratio of the numerical values of current(in amperes), resistance and time for which current flows is 5:2:10 and the heat generated is 8000 Joules. In building Elephanta, if the current that flows is 'I' amperes, the time for which it flows is (7 - 14/I) seconds. The heat generated in all circuits combined is 19667.6 Joules.
