Explanation:
Suspension bridges, like the Golden Gate Bridge or the Brooklyn Bridge, use tension force as the primary source of force that cables use to hold their spans up. The supporting cables receive the tension forces of the bridge, and this same force passes to the anchorages and into the ground
The total power delivered by the battery if the lightbulbs are connected is 9V^2/R
<h3>Power of a battery</h3>
The formula for calculating the power of a battery is expressed according to the equation;
Power = v^2/RT
where
R is the total resistance
v is the voltage or emf
If there are 3 identical lightbulbs, each having constant resistance R, then;
1/RT = 1/R + 1/R + 1/R
1/RT = 3/R
RT = R/3
The voltage drop across each lightbulbs will be the same for parallel connection, hence;
Power = 3V^2/(R/3)
Power = 9V^2/R
Hence the total power delivered by the battery if the lightbulbs are connected is 9V^2/R
