Question #6451

A 8 Ohms loudspeaker and a 8 Ohms loudspeaker are connected in parallel across the terminals of an amplifier. Assuming the speakers behave as resistors, what is the equivalent resistance of the two speakers?

_____________Ohms

_____________Ohms

Expert's answer

Because 8 Ohms loudspeaker and a 8 Ohms& loudspeaker are connected in parallel across the terminals of an amplifier and they are behaving as resistors we can apply formula for resistances in case of parallel connection:

&

1/R = 1/R1 + 1/R2 = 1/8+1/8 = 1/4 ==> R = 4 Ohms. - answer

&

1/R = 1/R1 + 1/R2 = 1/8+1/8 = 1/4 ==> R = 4 Ohms. - answer
