I think it's C, longer wave length.
<span>Humberto builds two circuits using identical components,
and then adds components to each circuit.
Circuit 1:
A series circuit with three lightbulbs.
Then add three more lightbulbs in series.
Circuit 2:
A parallel circuit with three lightbulbs
Then add two more lightbulbs on new branches
in parallel with each original bulb.
After adding the new lightbulbs in Circuit 1:
-- the voltage across each of the original bulbs is less,
-- the current through the whole series circuit is less,
-- the original three bulbs shine dimmer than before, and
-- the total power delivered from the battery is less.
-- The battery lasts longer.
After adding the new lightbulbs in Circuit 2:
</span>-- the voltage across each of the original bulbs is doesn't change,
-- the current through each original bulb doesn't change,
-- the original three bulbs shine just as bright as before,
-- the total currrent drawn by the circuit, and the total current
delivered by the battery, increases, and
-- the total power delivered from the battery increases.
-- The battery runs down sooner.
Yeah science is hard. Hopefully you do good in it :)
The answer for this would be A. since power is Joules/seconds and energy is rated in Joules
Explanation:
The peak emf in an AC generator is given by :
Here,
N is number of turns in the generator
A is area of the coils
B is magnetic field
is angular frequency
It is clear that the peak emf in an ac generator depends on :
- The number of turns in the generator
- Area of coils
- Magnetic field
