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

Resistance of a bulb is 500 Omega . It is connected to a battery of potential difference 220 V. How much current will flow through it?

A milliammeter gives full scale deflection when the potential difference across it is 5 volt and the current through it is 10 mA. How will you convert it into a voltmeter of range 0 to 100 volt?

If a sillicon solar cell of dimension 1 cm^(2) generates current of about 30 mA and potential difference of about 0.5 V. Find the current and potential difference generated by a sillicon solar cell of dimension 1000 cm^(2) .

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

A potential difference of 0.75 V applied across a galvanometer causes a current of 15 mA to pass through it . If it can be coverted into ammeter of range of 25 A , the required shunt should be

Solve the numerical problems: In the diagrams below, silicon solar cells with dimensions 1 cm^2 are connected. Find the potential difference and electric current?

Read the given passage and answer the following questions: The home electrical connection consists of 'live','neutral' and 'earth wires. The 'live' and the 'neutral' wires have potential difference of 220 v. The earth ire is connected to ground. Due to a fault in the equipment or if the plastic coating on the 'live ' and the neutral wires gives away the two wires come in contact with each other and a large current flows through it producing heat . If any inflammable material (such as wood , cloth , plastic etc). exists around that place it can catch fire. Therefore a fuse wire is used as a precautionary measures. Name the two wires having potential difference of 220 v.
