<h2>Answer:</h2>
24Ω
<h2>Explanation:</h2>
When resistors are connected in parallel, the reciprocal of their combined resistance, when read with a DMM (Digital Multimeter - for measuring various properties of a circuit or circuit element such as resistance...) is the sum of the reciprocals of their individual resistances.
For example if two resistors of resistances R₁ and R₂ are connected together in parallel, the reciprocal of their combined resistance Rₓ is given by;
=
+
Solving for Rₓ gives;
=
------------------(i)
From the question;
Let
R₁ = resistance of first resistor = 40Ω
R₂ = resistance of second resistor = 60Ω
Now,
To get their combined or total resistance, Rₓ, substitute these values into equation (i) as follows;
=
=
= 24 Ω
Therefore, the total resistance is 24Ω
Answer:
- The charge on the plates will increase with time
- The potential difference across the capacitor starts with zero and then increases gradually to a maximum value
- The current through the circuit starts high and then drops exponentially
Explanation:
<u>Case : An uncharged capacitor is connected to a resistor and a battery in a closed circuit.</u>
- The charge on the plates will increase with time
applying this equation : Q = as the value of (t) increases the value of Q increases i.e. charge on the plates
- The potential difference across the capacitor starts with zero and then increases gradually to a maximum value
applying this equation : V =
- The current through the circuit starts high and then drops exponentially
current : I =
