a. How much current will an electric bulb draw from a $220\ V$ source, if the resistance of the bulb filament is $1200\ Ω$ ?

[Note: Enter the answer up to two decimal places.]

$V$

$=$

$220\ V$

Resistance,

$R$

$=$

$1200\ Ω$

The formula is

$\begin{array}{l} I = \frac{i}{i} \\ = \frac{i}{i} \end{array}$

The current through the bulb is

$A$

b. How much current will an electric heater coil draw from a $220\ V$ source, if the resistance of the heater coil is $100\ Ω$ ?

[Note: Enter the answer up to one decimal place.]

$V$

$=$

$220\ V$

Resistance,

$R$

$=$

$100\ Ω$

$\begin{array}{l} I = \frac{i}{i} \\ = \frac{i}{i} \end{array}$

The current through the bulb is

$A$
