As current increases, the wires heat which can cause a fuse to blow or a circuit breaker to trip. As additional branches are added to a parallel circuit, the overall resistance of the circuit decreases. A decrease in resistance creates an increase in current.
<h3>What is a Simple circuit ?</h3>
A battery (or other energy source), a light bulb (or other energy-consuming device), and conducting wires that connect the two terminals of the battery to the two ends of the light bulb make up a simple electric circuit.
- Three elements make up an electric circuit: a power source, such as a battery or the mains. a lightbulb-like energy receiver an energy conduit, such as a wire

Answer: radio waves dont need a medium to travel through
Explanation:
Answer:
46°C
Explanation:
q = mCΔT
336,000 J = (20 kg) (4200 J/kg/°C) (50°C − T)
T = 46°C
Mass is Kg
Mol is the amount of substance
m is for meters
Answer:
The answer to your question is given below.
Explanation:
From the diagram given in the question, we can see that the bulbs are in parallel connection. This implies that different current will go through the bulb but the same voltage. But the resistance of each bulb is the same, therefore the same current current will go through them.
This can further be understood if we determine the current flowing through each bulb. This is illustrated below:
Voltage (V) = 30V
Resistant 1 (R1) = 15Ω
Current 1 (I1) =..?
V = I1R1
30 = I1 x 15
Divide both side by 15
I1 = 30/15
I1 = 2A.
Voltage (V) = 30V
Resistant 2 (R2) = 15Ω
Current 2 (I2) =..?
V = I2R2
30 = I2 x 15
Divide both side by 15
I2 = 30/15
I2 = 2A.
The overall current(I) in the circuit:
I = I1 + I2
I = 2 + 2 = 4A.
From the illustrations above, we can see that the same current will flow through each bulb as the will current split into two equal parts
