I mean say for example beta for the transistor is 100.

So the current gain for the load will be beta plus 1 (according to this website?)

How is this possible? I mean say the signal source places 4 volts across the load. the current say is X. Then the current going through the load should be 100x + 1 right? then if thats the case surely the voltage across the load will be V=RI : V = R[100Ibase +1]I would be something like over 400 volts?

Surely if the current going through a resistor increases the voltage across that resistor has to increase in accordance with ohms law??
