<span>If u want only WHether the total resistance is
less than 2 or less than 5 or more than 5 ohms: there is a Simple way.
When you connect resistances in parallel, resultant resistance is always
smaller than all of them. So it is less than 2 ohms</span>.
Velocity = distance (m) /time (s)
convert kilometers to metres (132300), substitute into formula.
convert hours to seconds (18000), substitute into formula. it becomes,
132300 divided by 18000 = 7.35 M/S
always answer questions in the units given in the question.
to get m/s into km/h, multiply by 3.6, therefore it equals 24.46 km/h
Answer:
R_eq = 6 Ω
Explanation:
In a series circuit the current is constant throughout the circuit and the resistance is the sum of all the resistances in it.
R_eq = ∑
in this case we have
R_eq = R₁1 + 3 R₂
where R₁ is the resistance of the fan and R₂ the resistance of each light, we must clarify that we will assume that the resistance of the lights does not change with temperature
let's calculate
R_eq = 3 + 3 1
R_eq = 6 Ω
