One solar panel produces a potential difference of 18 V and current of 3 A. Describe how you can obtain a potential difference of 72 volts and current of 9 A with a solar array using solar panels. You can use sign of a battery for a solar panel.

How much potential difference and electric current we can get from 100 cm^2 dimension of silicon solar cell?

How can you obtain the required amount of energy by connecting solar panels?

The potential difference between the terminals of a 6.0V battery is 7.2 V when it is being charged by a current of 2.0A.What is the internal resistance of the battery?

A parallel plate capacitor is charged to a potential difference of V volts. After disconnecting the charging battery the distance between the plates of the capacitor is increased using an insulating handle. As a result the potential difference between the plates

The internal resistance of an accumulator battery of emf 6V is 10(Omega) when it is fully discharged,As the battery gets charged up.its internal resistance decreases to 1(Omega) The battery in its completely discharged state is connected to a charger which maintains a constant potential difference of 9 V.Find the current through the battery (a)just after the connections are made and (b) after a long time when it is completely charged.

A voltmeter coil has resistance 50.0(Omega) and a resistor of 1.15k(Omega) is connected in series.It can read potential differences upto 12 volts.If this same coil is used to construct an ammeter which can measure currents up to 2.0A ,What should be the resistance of the shunt used ?

Lightning is very good example of natural current. In typical lightning, thereis 10^9 J energy transfer across the potential difference of 5 xx 10^7 V during a time interval of 0.2 s. Using this information, estimate the following quantities total amount of charge transferred between cloud and groung
