The potential difference across a variable resistor is 11V and the current flowing through it is 0.4A. What is the present resis
1 answer:
Answer:
27.5Ω
Explanation:
Given parameters:
Potential difference in the circuit = 11V
Current in the circuit = 0.4A
Unknown:
Resistance in the circuit = ?
Solution:
According to ohm's law;
V = IR
V is the voltage
I is the current
R is the resistance
Since the unknown is R, we find it;
11 = 0.4 x R
R = = 27.5Ω

Answer:
The value of gauge pressure at outlet = -38557.224 pascal
Explanation:
Apply Bernoulli' s Equation
+
+
=
+
+
--------------(1)
Where
= Gauge pressure at inlet = 3.70105 pascal
= velocity at inlet = 2.4
= Gauge pressure at outlet = we have to calculate
= velocity at outlet = 3.5
= 3.6 m
Put all the values in equation (1) we get,
⇒ +
=
+
+ 3.6
⇒ 0.294 = + 0.6244 + 3.6
⇒ = 0.294 - 0.6244 - 3.6
⇒ = - 3.9304
⇒ = - 38557.224 pascal
This is the value of gauge pressure at outlet.
