I hate maths. So I can't quite grasp the right answer for these questions, and since my Electronics lecturer is an *** and won't point me in the right direction... Can someone please answer:This:An amplifier delivers a power of 16W into a 4 Ohm speaker when the input is driven by a signal of 800mV RMS.Evaluate the RMS Voltage across the speakerEvaluate the gain of the amplifier in dB.And this please:A sinusoidal voltage source with a peak value of 50V is applied to a resistive load of 10 Ohms. Calculate the power in the load.They're doing my head in. Can you also include how oy uwork em out, so I can see if I can repeat the results? Thanks.
