sesenic [268]

Answer : First of all, to harness the solar energy and utilize it for the decomposition of water to make hydrogen fuel cell seems to be easy but practically it has many hurdles in its way. It might not work well, when the days would not be sunny. Also, the production of hydrogen fuel would require decomposing water which may need a high energy of activation, which would be more than the energy that will be produced from the fuel cell.

A voltage amplifier with an input resistance of 40k ohms, an output resistance of 100 ohms, and a gain of 300 V/V is connected b
AfilCa [17]

Answer:

89.45 v/v

Explanation:

Let's take the data:

First draw the amplifier circuit.

After the circuit, the voltage division rule can be used to compute the parameters:

The input section is computed like this: \frac{R_{in} }{(R_{sig}  + R_{in} }  (v_{sig})

The output section is computed like this R_{L}/ (R_out}  + R_{in} )

The product AV_{in} V_{out} gives

AV_{in} V_{out}  = A×\frac{R_{in} }{(R_{sig}  + R_{in} }  (v_{sig})×R_{L}/ (R_out}  + R_{in} )

Computing gives output voltage = 89.45 v/v
