    Someone please tell me why CRO is placed between resistor but not across capacitor in a simple RC circut ??

    I didn't get really your question, But anyway, If a CRO was placed across the capacitor as it was being charged, then the voltage would rise rapidly at first, then progressively slow down to imperceptibly stop at the voltage value of the charging battery.

    But in case we're discharging the capacitor, Then a CRO across the resistor, which is also now across the capacitor will show a decaying voltage, The current will also show the same graph.

    Hope I answered your Question :)
