Answer:
<em>The current is 1 A</em>
Explanation:
<u>Current in a Series Connection
</u>
When two or more elements are connected in series, all of them have the same current, and the sum of their individual voltages is the total voltage applied to the circuit.
According to Ohm's law:
V=R.I
Where V is the voltage, R is the resistance and I is the current of a circuit.
We have a voltage of V=1.5 V + 1.5 V = 3 V and a resistance of R=3 ohms.
We can calculate the current by solving for I:
The current is 1 A
Answer:
D and E
Ionic bonds are formed between metals and non-metals and both of those are metals
Answer:
The new voltage between the parallel plates of the capacitor is 18V, because for a constant electric field, doubling the space between the parallel capacitor plates, will also double the potential difference (voltage) between the plates.
Explanation:
ΔV = E*Δd
Where;
ΔV is the change in potential difference
Δd is the change in the distance between the parallel plates
E is the electric field potential.
Assuming a constant electric field; 
when the spacing between the capacitor plates is doubled, d₂ = 2d₁
v₂ = (v₁*d₂)/(d₁)
v₂ = (v₁*2d₁)/(d₁)
v₂ = 2v₁
v₂ = 2(9) = 18 V
Therefore, for a constant electric field, doubling the space between the parallel capacitor plates, will also double the potential difference (voltage).
